Adjusting communication capacity in a multi-stage routing network

A non-transitory computer-readable storage medium including instructions that, upon execution, cause a computer system to:

• detect that a number of active connections between a first router in a first stage of a multi-stage router network is below a first threshold number;
• detect that a number of active connections between a second router in the first stage of a multi-stage router network is below a second threshold number;
• detect that one or more routers in an adjacent second stage of the multi-stage router network is below the first threshold number;
• and
• send a notification based on the number of active connections for the first router falling below the first threshold number and the number of active connections for the second router falling below the second threshold that the first and second routers are unavailable so that communications to the first stage are routed to one or more other routers in the first stage.

A system, comprising:

• a plurality of routers in a multi-stage router network, the plurality of routers arranged in at least a first stage, a second stage and a third stage of the multi-stage router network;
• and
• a router monitoring service communicatively coupled to the plurality of routers, the router monitoring service operable to:
• monitor a number of available connections between a first router in the first stage of the multi-stage router network, a second router in the first stage of the multi-stage router network, and one or more of the plurality of routers in the second stage of the multi-stage router network;
• detect that the number of available connections to the first router falls below a first threshold number;
• detect that the number of available connections to the second router falls below a second threshold number;
• send a notification to one or more of the plurality of routers in the third stage of the multi-stage router network based on the number of available connections for the first router falling below the first threshold number and the number of available connections for the second router falling below the second threshold number that the first and second routers in the first stage are deprioritized;
• and
• operate the one or more routers in the third stage so that communications to the first stage are routed to one or more other routers in the first stage.
